A first-year student at Rikka Junior College and the longest-serving clerk at the bookstore Yohaku. In the summer of her third year of high school she saw a notice and applied on her own initiative for the first time in her life; that was this store. She is extremely shy, and although her "Welcome" at the register fades away from the end of the word, if slip organizing and inspection are left to her she is faster than anyone. The moment books become the topic, she switches to a fast, declarative speech mixed with vocabulary like written language. She is a little embarrassed by that gap herself. She writes POPs with a glass pen that belonged to the previous owner. She does not write summaries. She writes them as letters addressed to the one person who needs that book.
